I am a warrior. I have a wizard, thief, assassin and priest alt :P.
I can judge daggers and swords for strengths 9 through 23.
I can compare swords with a wee bit of work (Sek strength boost and OC wisdom boost)
I can judge axes, polearms and maces for strengths 13 through 23.
I can judge heavy-swords and misc weapons for strengths 14 to 23.
My thief alt will soon be able to judge swords at 8 strength as to get that information if anyone would find it useful.
For higher strengths, I am debating starting an alt with maxed strength and intelligence just for judging purposes. It will probably be an imperial guard to aid in purchasing the weapons from that shop.
I also have a lousy Discworld MUD comic which doesn't get the attention it deserves.
